Investigation of the accuracy of determination of coordinates of location points by VLP-16 laser scanner installed on DJI S1000 UAV

Abstract

Goal. The aim of the work is to study the accuracy of determining the coordinates using a laser scanner laser scanner VLP-16 mounted on an octocopter DJI S1000. The authors implemented the technological scheme of installation of the VLP-16 laser scanner on the DJI S1000 octocopter and the method of studying the accuracy of determining the spatial coordinates of the points of objects with a laser scanner. The Department of Photogrammetry and Geoinformatics has developed a high-tech integrated complex of UAVs helicopter type DJI S1000 with air laser scanner Velodyne Lidar VLP- 16. As a result of creation of a complex the completely unified system without additional manufacturing of precision details and knots is received. For the S1000 helicopter-type UAV, test flights were performed to determine the accuracy of the obtained spatial coordinates using a scanner mounted on the body of the octocopter, the results were respectively: mX = 0.04 m, mY = 0.03 m, mZ = 0.04 m. The obtained results should be applied to the complex for various topographic and applied problems. Results. The proposed complex was tested at the appropriate control points obtained during aeroscanning with UAVs at control points, which made it possible to justify the effectiveness of the proposed method. Scientific novelty. For the first time, a compact, active VLP-16 laser scanner was tested on an DJI S1000 octocopter UAV. Practical significance. The obtained data from laser scanning can be used to solve various engineering problems. Namely, the creation of 3D-models of architectural structures, determining the volume of quarries, creating digital models of engineering and transport infrastructure: power lines, infrastructure of roads and railways, reconstruction of architectural monuments, research of channel processes, quantitative determination indicators in forest assessment.
